I received a call on March 10th at 7:47pm and I did not answer it. I next looked at my phone after midnight, so the date was now March 11th, and of course it showed me my missed call.

Now when I go into the phone application and see the call log list, it shows the missed call as being on March 11th. However, if I go into the Messages application and go to the "Missed Calls" folder, it lists 7:47pm on March 10th. There are no other calls from or to this number on my call log.

And I have a similar thing with a call I made to check my voicemail. Again, in the phone application, it shows the date as being one day later. But when I check the Messages application and go to the "call log" folder, the date and time are correct.
